  • 在看waters 600e的说明书,其中有段安装ferrule的内容,看的不是很懂,ferrule最后是怎么卡在不锈钢管上的?

    图和文字描述如下:请求高手详解,谢谢!


    Assembling a Standard Ferrule Connector
    1. Slide the compression screw onto the tubing end (see Figure 2-4). Slide the ferrule
    onto the tubing with the broad end of the taper toward the screw.
    2. Push the tubing all the way into the fitting body until the tubing bottoms out. The
    fitting body can be a stainless steel union, a column end, or any part of the system
    that has a female receptacle.
    3. While you hold the tubing securely in place (bottomed out), finger-tighten the
    compression screw.
    4. Using a 5/16-inch wrench, tighten the screw an additional 1/4-turn. This seats the
    ferrule against the tubing and prevents it from coming off when you disconnect the
    tube.
    5. Remove the assembled fitting and verify that the length of tubing extending beyond
    the ferrule is equal to the length of tubing of other fittings previously installed.

    ferrule开始是很松的可以滑动,当你将钢管连接到系统时要用扳手上紧,当你上紧后ferrule自然抱紧不锈钢管就不能再取下了,所以在上紧时一定要摆放正,偏了就要报废一个刃环了。
